This wonderful route Climbs Cwm Bwchel to Bal Mawr, heads along the ridge to Chwarel y Fan and descends to Capel y Ffin. There is a steep climb up to Offa’s Dyke and drop into the Olchon Valley to take in the Red & Black Darren loop, with an optional scramble. This loop can be left out if the weather on the day is rubbish. Final descent back to Llanthony Priory
